چکیده مقاله
The Dehnow anticline, a NW–SE trending salt detached box fold in southern Iran, constitutes a structural trap and is considered a promising target for hydrocarbon exploration within the Zagros Fold and Thrust Belt, in the Fars sedimentary basin Previous geophysical investigations, including seismic reflection, potential field, and magnetotelluric surveys, have delineated its framework and indicated the presence of approximately 11–15 km of sediment overlying the Hormuz salt, which serves as a regional detachment horizon In this study, we apply gravity data inversion with bound constraints, a depth weighting function, and mixed 𝐿𝑝 norm regularization to improve the geological plausibility of the recovered models and more precisely characterize the anticline’s trap structure The resulting density contrast models are compared with a seismic reflection profile from the adjacent Lavarestan anticline, used as a reference, to assess which inversion configuration best corresponds to the independent seismic observation The findings confirm a structurally valid trap above the Hormuz salt and highlight the potential of the Dehnow anticline as a viable drilling target
